That's something I do believe is a strong possibility, which is one of the reasons why this whole bad penalty thing pisses me off even more. The consistency with which we have been snakebitten by these bad calls at the most inopportune times, like the phantom OPI on Cook or the phantom defensive holding on Sim right after a huge sack of Romo gets into these players (and coaches) heads. It makes them play tentatively, and worse, makes them start over thinking things. Instead of focusing on running a good route, getting to the QB, etc., they start thinking first about how to avoid a penalty, or in JJ's case, how to make a big play to overcome the shaft we just got.
This is a young team learning how to win, and it's tough enough to learn how to play well for 60 minutes and overcome your own mistakes. When you add the psychological burden of always having to look over your shoulder for a flag even though you played it right, it becomes that much more difficult to get over the hump. Fisher needs to raise holy hell with the NFL officiating front offices, and he needs to get Kroenke involved if it keeps getting worse. If the bad calls continue to dog us as persistently as they have so far, I guarantee this team will not get over the hump, at least not this year.
